Building thoughtful, performant interfaces for the modern web. Passionate about clean code and delightful user experiences.
Hi, I'm Karin — a software engineer with a deep passion for building products that are both beautiful and functional. I specialize in front-end engineering with a strong command of modern JavaScript ecosystems.
When I'm not writing code, I enjoy exploring UI design patterns, contributing to open-source, and continuously pushing the boundaries of what's possible on the web.
